Non-equilibrium quantum transport is crucial to technological advances ranging from nanoelectronics thermal management. In essence, it deals with the coherent transfer of energy and (quasi-)particles through channels between thermodynamic baths.

Quantum speed limits (QSLs) impose fundamental constraints on the evolution of quantum systems. For systems with time-independent Hamiltonians, QSLs are intricately linked to energy spectra initial state, which signify generalization time-energy uncertainty relation. Based arbitrary-order norms Hamiltonian, dual energies from inverted spectra, and standard deviation energy, different types have been proposed, revealing three dynamical parameter regimes state evolution. Despite theoretical...

Quantum many-body scarring (QMBS) -- a recently discovered form of weak ergodicity breaking in strongly-interacting quantum systems presents opportunities for mitigating thermalization-induced decoherence information processsing. However, the existing experimental realizations QMBS are based on kinetically-constrained where an emergent dynamical symmetry "shields" such states from thermalizing bulk spectrum.

Quantum speed limits (QSLs) impose fundamental constraints on the evolution of quantum systems. Traditionally, Mandelstam-Tamm (MT) and Margolus-Levitin (ML) bounds have been widely employed, relying standard deviation mean energy distribution to define QSLs. However, these universal only offer loose restrictions evolution. Here we introduce generalized ML bounds, which prove be more stringent in constraining dynamic evolution, by utilizing moments spectra arbitrary orders, even noninteger...
